Developers describe DC/OS as "The Datacenter Operating System. The easiest way to run microservices, big data, and containers in production". Unlike traditional operating systems, DC/OS spans multiple machines within a network, aggregating their resources to maximize utilization by distributed applications. On the other hand, Apache Mesos is detailed as "Develop and run resource-efficient distributed systems". Apache Mesos is a cluster manager that simplifies the complexity of running applications on a shared pool of servers.

DC/OS and Apache Mesos can be primarily classified as "Cluster Management" tools.

Some of the features offered by DC/OS are:

High Resource Utilization

Mixed Workload Colocation

Container Orchestration

On the other hand, Apache Mesos provides the following key features:

Fault-tolerant replicated master using ZooKeeper

Scalability to 10,000s of nodes

Isolation between tasks with Linux Containers

"Easy to setup a HA cluster" is the top reason why over 4 developers like DC/OS, while over 19 developers mention "Easy scaling" as the leading cause for choosing Apache Mesos.

DC/OS is an open source tool with 2.17K GitHub stars and 458 GitHub forks. Here's a link to DC/OS's open source repository on GitHub.

According to the StackShare community, Apache Mesos has a broader approval, being mentioned in 61 company stacks & 19 developers stacks; compared to DC/OS, which is listed in 19 company stacks and 12 developer stacks.

What are some alternatives to DC/OS and Apache Mesos?

Kubernetes

Kubernetes is an open source orchestration system for Docker containers. It handles scheduling onto nodes in a compute cluster and actively manages workloads to ensure that their state matches the users declared intentions.

Docker

The Docker Platform is the industry-leading container platform for continuous, high-velocity innovation, enabling organizations to seamlessly build and share any application — from legacy to what comes next — and securely run them anywhere

OpenStack

OpenStack is a cloud operating system that controls large pools of compute, storage, and networking resources throughout a datacenter, all managed through a dashboard that gives administrators control while empowering their users to provision resources through a web interface.

Marathon

Marathon is an Apache Mesos framework for container orchestration. Marathon provides a REST API for starting, stopping, and scaling applications. Marathon is written in Scala and can run in highly-available mode by running multiple copies. The state of running tasks gets stored in the Mesos state abstraction.

Rancher

Rancher is an open source container management platform that includes full distributions of Kubernetes, Apache Mesos and Docker Swarm, and makes it simple to operate container clusters on any cloud or infrastructure platform.
